WILLIAM A. STEPHENS, OF NASHVILLE, KANSAS.

COVERING ATTACHMENT FOR LISTERS.

To all whom it may concern:

Be it known that I, W'ILLIAM A. S'rn- PHENS, a citizen of the UnitedStates, residing at Nashville, in the county of Kingman and State ofKansas, have invented certain new and useful Improvements in CoveringAttachments for Listers, of which the following is a specification,reference being had to the accompanying drawings.

My invention relates to new and useful improvements in attachments forlisters and more particularly-to a covering attachment therefor, and myobject is to provide a device of this character which may be readily andquickly attached to a listcr of any design, whatsoever, and which willeffectively cover the seed planted by the lister.

A further object of the invention resides in the provision of a devicehaving a pair of covering disks thereon and means for the adjustment ofsaid disks to various angles.

A further object of the invention resides in the provision of a deviceformed of a pair of sections, upon which are rotatably sup ported thecovering disks and means for the adjustment of said sections at anglesto one another to correspondingly dispose the covering disks at suchangles.

A still further object of the invention re- 1 sides in the provision ofa sectional arch between the sections of the device, which seetions ofthe arch are pivotally connected with one another to compensate for thedisposing of the sections of the device at various angles to oneanother.

A still further object of the invention re- I sides in the provision ofa device which is extremely simple in construction, thereby readily andcheaply manufactured, and one which is very effective and useful inoperation.

WVith these and other objects in view, my invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification and claims.

In the accompanying d 'awings forming a part of this application, Figure1 is a side elevation of the device. Fig. 2 is a top plan view thereof.Fig. 3 is a rear elevation.

Specification of Letters Patent.

Application filed August 12, 1911.

Patented Dec. 19, 1911.

Serial No. 643,748.

Fig. 1 is a section as seen on line 4-4, Fig. 2, and, Fig. 5 is asection through the device as seen on line 5-5, Fig. 1.

In carrying out my invention, I shall refer to the drawings in whichsimilar reference cha 'acters designate corresponding parts throughoutthe several News and in which 1 and 2 indicate, respectively, a pair ofboxings square in cross section and provided with the central horizontalbores 3 and 4, respectively. Disposed in said bores 3 and t, so as torotate therein, are the sleeves 5 and (3, the outer ends of which areprovided with the integral heads or washers 7 and 8, respectively, thebores of said sleeves being somewhat restricted and extending completelythrough the heads thereof, and extending through the bores of saidsleeves, are the spindles 9 and 10 which are, respectively, provided ontheir inner ends with the integral heads or washers 11 and 12. The outerends of said spindles project a short distance beyond the outer faces ofthe head 7, and mounted thereon, are the covering disks l3 and 14,respectively. The extreme outer ends of said spindles are threaded andhave engaged therewith, the nuts 15, whereby said disks may be securelyheld thereon and the spindles and sleeves retained in position withinthe boxings.

Each of the boxings or members 1 and 2, is provided on its front facewith a pair of lugs 16, which lugs are slotted, as shown at 17, and eachis provided with an opening 18 which extends vertically thcrethrough. Apair of bars 19 and 20 is also provided, the

one end of each of which is disposed in the slot of the outer of eachpair of lugs 16, and pins 21 are passed through the vertical openings 18in said lugs and through the ends of said bars, whereby the latter willbe pivotally connected to said lugs. Said bars 19 and 20 are also bentintermediate of their ends toward one another so as to be securedtogether in any desired manner, as shown at 22, and the extreme freeends of said bars are slightly separated and provided with openings,whereby the same may be readily secured or engaged with a lister frameor the like.

At the point at which the pair of bars 19 and 20 are clamped to oneanother, is fulcrumed a lever 23, the lower end of which has pivotedthereto, the ends of a pair of bars 24 and 25. The opposite ends ofthese bars are inserted in the slots of the inner being operable bymeans of the usual grip 28 pivotally carried on said lever. In thismanner, it will be seen that by the movement of the lever, the boxings 1and 2 may be disposed at various angles to one another tocorrespondingly dispose the covering disks 13 and 14 at similar angles,but in order to limit the movement of said boxings 1 and 2 and preventthe entire separation of the same during the operation of the device,the arch 29 is provided, which arch is formed in sections. The sectionsof this arch are pivoted together about centrally of the horizontalportion thereof, as shown at 30, and the arms or vertical portions ofsaid arch are disposed in the vertical openings of the lugs 31 and 32formed on the rear faces of the boxings 1 and 2, respectively, said armsor vertical portions of the arch being provided with openings adjacenttheir ends in which are entered the bifurcated or cotter-pins 33,whereby said arch may be retained in its effective position. Saidboxings or members 1 and 2 are also provided on their upper faces withthe openings 34 which extend therethrough to the bores therein, andthrough the medium of these openings 34:, the rotating sleeves whichsupport the spindles carrying the disks, may be readily lubricated.

It is a well known fact that in the use of covering attachments forlisters, difiiculty has been experienced in obtaining a lister, thecovering blades of which may be adjusted to throw sufficient soil tocover deep furrows, and it will be seen that in the use of the device,such as I have provided, the sections thereof may be disposed at suchangles as to cause the blades or disks to engage the banks of the soiland throw the same into the furrow where seed has been planted.

In the use of my device, it will be seen that the washers or heads ofthe spindles of the respective boxings, are adapted to contact with oneanother, as said boxings are forced to the various angles through themedium of the lever, and it will still further be seen that in thevarious movements of the boxings, the sectional arch remains inengagement therewith to prevent complete separation thereof.

It will further be seen that this device may be readily attached to alister of any type, whatsoever, thereby eliminating the necessity of anentirely separate machine.

It will still further be seen that my device is of simple and durableconstruction, may be cheaply manufactured, and is one which will be veryeffective and useful in operation.

What I claim is 1. An attachment for listers, comprising a pair ofsections, flexible connecting means therebetween, covering disksrotatably carried on said sections, bars pivotally secured to saidsections and adapted to be attached to a lister, a lever fulcrumed onsaid bars, additional bars pivoted to said sections and engaged with oneend of said lever, whereby said sect-ions may be disposed at variousangles to one another.

2. An attachment for listers, comprising a pair of boxings provided withlugs on their rear faces, a U-shaped linking member formed in sections,the sections of which are pivoted to one another and have their arms,respectively, engaged in the lugs on said boxings, covering disksrotatably carried on said boxings, means to attach said boxings to alister, and additional means to dispose said boxings at various anglesto one another.

3. An attachment for listers, comprising a pair of sections, flexibleconnecting means therebetween, covering disks rotatably carried on saidsections, said sections being each provided on their outer faces with apair of laterally extending lugs, a pair of bars pivotally engaged atone of their ends to a lug on each of the sections, an additional pairof bars having one of their ends pivotally engaged with the remaininglugs on said sections, and a lever fulcrumed on the first referred topair of bars and having the -lower end thereof pivotally engaged withthe opposite ends of said additional pair of bars, whereby said sectionsmay be disposed at various angles to one another.

at. A11 attachment for listers, comprising a pair of sections being eachprovided on their rear faces with a lug, a U-shaped connecting memberformed of sections-pivoted to one another, the arms of said U member Iadditional pair of bars having the inner ends thereof pivotally engagedwith the remaining lugs on the front faces of said sections, and a leverfulcrumed on the first referred to bars and having the lower end thereofpivotally engaged with the forward ends of the additional bars.
